Inside the girl's Soul on the battlefield
"I wish that I could have been a better sister to Rex." The girl watched Rex's battle.
She had already disappeared from the battlefield.
"Oh looky here." A demonic voice said.
The girl looked up and saw a demon with a book. The demon noticed her when no one else could.
"I am a special demon. I have the power to grant wishes. The problem lies with the consequences of granting the wish."
The demon showed the book to the girl. She began to scroll through. Seeing the wishes granted was good but the flip page showed the consequences.
The consequences were nearly too much for the person to handle without the demon. She wanted to just leave, but she knew that if there was another chance to become Rex's brother. It would have to be with the demon and she did not know what the consequences would be.
"What would be the consequence of becoming Rex's sister?" The girl asked.
The demon smiled and looked at his consequence page. He thought that something was wrong when he read the page. The page was blank, he began scrolling through the rest of the book.
"Something is wrong. I do not know what the consequence will be." The demon replied.
The girl closed her eyes. She nodded yes that was her wish.
The demon looked at the consequence page. He was completely baffled at the consequences.
"The consequence of asking for that wish is fighting him on his home planet." The demon answered.
The girl looked confused. She did not know that Rex was not from the Nine Realms. Although she was certain that some people were not, she felt that he had always belonged in the Nine Realms.
"I will accept the consequences." The girl answered.
The book had an eerie glow to it and the demon's body seemed to become golden.
"Your wish is to become that man's little sister for your wish correct?" The demon asked.
The girl pointed to where Rex was standing. "Confirmation of the target. Now to the consequence of that wish."
The demon seemed to glow red this time.
"You will have to fight him. Even though you love and trust him. Are you positive that you can throw a punch or a kick to show that you can fight?" The demon asked.
"I will do whatever it takes." The girl screamed.
"Confirmation of the buyer's agreement. The conclusion is we will have to travel to get to his home planet."
The girl accepted.
The two started to train her little body. It was not long five years but it was good enough for her body to get the basics.
"I am ready to leave." The girl announced.
"Alright. Let us leave the battlefield then." The demon spoke inside her Soul.
Upon exiting it, she found that things had changed drastically. There were now portals that lead to the waring Era. She was baffled by how much it changed.
She went and got into a safe location. The demon went and sent her to the Second Realm.
The girl entered Lumi and found Rex walking around with Olivia. Although the girl was jealous. She saw that Rex was treating her normally and not like a spouse.
"I may still have a chance." The girl jumped inwardly in joy.
The demon found it amusing that the girl wanted more than to be Rex's sister. The demon also felt how strong Rex was.
"We have to take full advantage of when he sleeps." The demon said.
The demon assured her that everything would be fine. To become Rex's sister, the demon used a demonic connection.
"This way we can travel to his world."
The girl nodded.
Rex finally went back to Earth.
Current time
The girl is watching the demon use her body to lightly fight Rex. Although Rex is giving his all, the demon is not allowing Rex to hurt the girl's Soul.
"I have to fight!" The girl shouted.
Her shout was heard and Rex stopped. The girl threw a punch. The demon thought it was funny how powerful she thought she was.
The girl heard, "Congratulations for throwing a punch at Rex. You can now fight to become his sister."
She looked and the demon and his book had disappeared. She was saddened but she looked to Rex.
The girl shouted again, "I will fight. I have to become your sister and one day, have... your...baby." She stuttered at the end.
Rex was baffled to hear this. Liz decided she did not hear what the little girl wanted. Iris was still a long way away.
"Why do you want to become my sister?" Rex asked.
The girl started to twiddle her thumbs. She was super worried about the response she was going to give.
"You and I go way back. I always loved you and you always did your best for me." The girl was blushing. "I asked you for marriage and you said, "I cannot guarantee it. I will guarantee you that you can become my little sister." With that I found a path to become your sister." The girl was redder than a bright red shirt.
Rex felt a headache coming on. Liz had put Iris on the phone and let Iris hear what the girl was saying. Iris was completely defeated and she was going to fight Rex. She was not going to allow him to have a little sister.
"I better prepare myself." Iris said when she hung up.
She focused on her Water affinity and formed several swords.
Each sword began to dance around Iris. Nothing was stopping her now that, she had to fight Rex. She had let enough be enough.
"I am coming to protect you." Iris said walking through blasting the walls and cars away.
The closer she got the more she felt like everything was never going to be right unless she fought herself.
"This fight is for me to have Rex's heart, Soul, and body." Iris continued the saying till she reached the house.
"REX! I DEMAND THAT YOU AND I FIGHT! I AM FIGHTING TO HAVE YOUR HEART, SOUL, AND BODY TO MYSELF!" Iris shouted at the top of her lungs.
The water swords echoed her words. The inside of the house nearly became a concert with Iris shouting.
Rex, Liz, and the little girl exit the house. They saw Iris using her water swords and that she was ready to fight.
